Evangelical theology – What is it?

WHAT DOES THE BIBLE SAY?

Evangelical theology takes its name from the biblical word for “gospel,” euangelion, and focuses on what Scripture teaches about God’s saving work in Jesus Christ. The Bible presents the gospel as the message that Christ died for sins, was buried, and rose again on the third day (1 Corinthians 15:3–5), and evangelical theology views this as the center of Christian faith. Scripture also teaches that salvation is received by grace through faith rather than by works (Ephesians 2:8–9) and that each person must experience new spiritual life through the work of the Holy Spirit, referred to as being born again (John 3:3).

Evangelical theology, therefore, holds the Bible as the final authority for faith and practice (2 Timothy 3:16–17) and emphasizes the need for individuals to trust in Christ personally. It also affirms the responsibility of believers to make the gospel known, in line with Jesus’ command to make disciples of all nations (Matthew 28:18–20). In this way, evangelical theology reflects the core biblical teachings about salvation, Scripture, and the mission of the church.

FROM THE OLD TESTAMENT

• God’s revelation is written, preserved, and binding (Deuteronomy 6:6–9; Psalm 19:7–11). This supports evangelical theology’s emphasis on Scripture as the final authority.
• Abraham “believed the LORD, and He counted it to him as righteousness” (Genesis 15:6), showing that right standing with God comes by faith, not works.
• The Old Testament anticipates a coming Savior (Isaiah 53; Jeremiah 31:31–34), grounding the gospel-centered focus central to evangelical belief.
• God desires inward change, not mere ritual (Psalm 51:16–17; Ezekiel 36:26–27), aligning with the evangelical emphasis on personal conversion.

FROM THE NEW TESTAMENT

• The New Testament uses the Greek word euangelion (“gospel” or “good news”) to describe God’s saving message. The word “evangelical” comes from that Greek word. For example, Paul wrote, “For I am not ashamed of the gospel (euangelion), for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek” (Romans 1:16).
• Evangelical theology treats Scripture as authoritative. Paul wrote, “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work” (2 Timothy 3:16–17). Because Scripture comes from God and equips believers for every aspect of life and godliness, it stands as the foundation of the Christian faith.
• Paul also provided a simple summary of the gospel that the early church affirmed: “that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve” (1 Corinthians 15:3–5). Through Jesus’ death and resurrection, God offers forgiveness, reconciliation, and new life to those who believe in Him.
• Jesus taught that salvation requires an inward work of the Holy Spirit. He said to Nicodemus, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God” (John 3:3). The new birth shows that salvation is not achieved by outward realities, such as religious tradition or human effort, but through the Spirit’s internal work.
• Evangelism is the ongoing work of the church, carried out as believers share the good news and instruct others to obey Christ. Jesus commanded His followers, “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age” (Matthew 28:19–20).

IMPLICATIONS FOR TODAY

The plot of the old Mission Impossible series and movies started with the famous line, “Your mission should you choose to accept it . . .” The heroes always accepted it. The mission of evangelical Christians that we must accept is telling others about Christ (Matthew 28:19-20). The stakes couldn’t be higher: We are all accountable to God for our sin, which separates us from God who will enact judgment in keeping with His holy, just character. On our own, we cannot escape that judgment. This is why the gospel is so significant: God provides the answer to a problem we cannot solve. His Son, who took on humanity and lived without sin. Jesus did not owe that penalty, yet He chose to die so that the Father could punish Him in our place. His sacrifice satisfied God’s wrath and opened the way for us to be saved.

Maybe you’ll respond, “But I’m not evangelical. I’m a Christian.” But put the argument aside and open the Bible. The mission is there, from Jesus' own words in Matthew 28:19-20: “Go therefore and make disciples of all nations, baptizing them in[b] the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” If we love our Lord and Savior, this is a mission we cannot turn down.
